Nelson Browning, DO
Magic Valley Program 2026
Dr. Nelson Browning had ties to medicine from day one. He was born suddenly and rather unexpectedly–right on the kitchen floor! As a result, he earned the nickname “Chef Browning” by his pediatrician who instilled in him a love of healthcare from a young age. He grew up just outside of Seattle, Washington, where he enjoyed living close to the outdoors. His family routinely traveled to Idaho to visit extended family, and at age 16, they moved to eastern Idaho permanently. Although a rather significant change, Nelson grew to love Idaho and call it home. After graduating from Rigby High School, he served a two-year mission for The Church of Jesus Christ of Latter-Day Saints in San Bernardino, California.
While attending Brigham Young University – Idaho for his undergraduate education, Dr. Browning explored potential career options and skills outside of healthcare, such as accounting, engineering, and secondary education. Ultimately, he continued to be drawn to biological sciences and caring for others. While at BYU – Idaho, he met his wife, Kaylee. An Idaho native from Sugar City, Kaylee is an avid sewer and quilter. She also graduated with an associate degree in art and has her cosmetology license. They moved to Iowa in 2019 where Dr. Browning attended medical school at Des Moines University. Grateful for the opportunity to explore the midwest, but also mildly homesick, he and Kaylee are excited to be back in Idaho and living in the Magic Valley.
In his spare time, Dr. Browning loves to drum and listen to music. He enjoys movies, camping, hiking, biking, and spending time outdoors. He and his wife like to travel and try new restaurants. He loves good barbecue or a classic burger and hopes to someday visit and eat at a local restaurant in every US state.
Michael Dialogue, MD
Magic Valley Program 2027
Dr. Michael “Mike” Dialogue grew up in Nampa, Idaho with a family that cherished time together, spending as much time as possible riding dirt bikes in the desert, camping in the mountains, and playing games together at home. During high school, he also added drama and theater to his list of hobbies and was very fortunate to play roles such as Petruchio from Shakespeare’s Taming of the Shrew, Mr. Darcy from Pride and Prejudice, and The Beast from Beauty and the Beast. His mother instilled in him a deep love for learning and reading at a very young age. It was this combined with his passion for science that pointed him on the path towards medicine.
After high school, he had the opportunity of a lifetime to serve a two-year church mission for The Church of Jesus Christ of Latter-Day Saints to Hokkaido, Japan, where he lived and served in very isolated rural parts of Japan. Upon completing his mission he returned to Idaho to attend Idaho State University, and it was there where he met and married his wife. They have three young children, one boy and two girls. Upon completion of his undergraduate degree in biochemistry, he returned to his hometown of Nampa to attend the Idaho College of Osteopathic Medicine.
His hobbies now include mountain biking as much as he possibly can, getting outside (often on bikes) with his wife and kids, reading, and going on adventures with them. He and his family are thrilled to be in the Magic Valley now to continue his training. They look forward to the new opportunities they will discover here and to meeting new people along the way.
Marta Wooldridge, MD
Magic Valley Program 2027
Dr. Marta Wooldridge grew up in Poland and graduated from the Medical University of Gdansk. During one of her summer breaks, she journeyed to Idaho for a work-travel program.

After graduation, Marta moved to Ketchum, Idaho where she married and started a family.
Before residency, Marta had an opportunity to complete student rotations with family medicine doctors in the Wood River Valley. This experience introduced her to the world of full-spectrum family medicine and inspired her to follow this path. Marta is extremely excited to join the Magic Valley Residency Program. In the future she sees herself working with rural and underserved communities, and being a beacon of health awareness.
In her spare time, Marta can be found outdoors exploring Idaho’s majestic mountains, biking, skiing, camping, and spending time with friends and family.
Mark Keele, DO
Magic Valley Program 2028
Idaho College of Osteopathic Medicine
Dr. Mark Keele grew up in Boise, Idaho, where his love for medicine took root early on during his years at Timberline High School. He later attended Brigham Young University, graduating with a degree in Microbiology, and spent four years working as a dermatology medical assistant during his undergraduate studies. Through assisting with skin exams, biopsies, and excisions, he developed a deep appreciation for the role family physicians play in detecting and treating skin cancer early—an area that continues to drive his clinical interests today.
He took a two-year break from school to serve a mission in Stockholm, Sweden for The Church of Jesus Christ of Latter-day Saints, where he learned to speak Swedish and gained a deep appreciation for serving diverse populations.
During medical school at Idaho College of Osteopathic Medical School in Meridian, Mark’s interest in full-spectrum family medicine expanded to include emergency care, obstetrics, dermatology, and preventive medicine—including skin examinations and colonoscopies to improve long-term patient outcomes. His favorite aspect of medicine is forming lasting relationships with patients while offering care across all life stages.
Outside the hospital, you’ll often find Mark rock climbing, playing pickleball, or watching BSU/BYU football. He and his wife stay busy raising their three kids and love engaging with the community—especially through youth sports and outdoor family adventures. He’s excited to be continuing his training in the Magic Valley, close to the people and places that feel like home.
Edgar Sanabria, MD
Magic Valley Program 2028
Universidad Nacional Autonoma de Honduras Facultad de Ciencias Medicas
Dr. Edgar Sanabria was born and raised in San Pedro Sula, Honduras. After graduating from the Universidad Nacional Autónoma de Honduras in 2016, he gained valuable clinical experience working in underserved areas like Puerto Cortés and El Progreso.

These early experiences shaped his approach to patient care, focusing on compassion and accessibility.
In addition to his clinical work, Dr. Sanabria has volunteered as a medical interpreter and physician with Faith and Humanity Medical Missions, a U.S.-based nonprofit that brings medical care to rural communities in Honduras. This role has further deepened his understanding of healthcare disparities and the importance of providing care where it’s needed most. Dr. Sanabria has also had the opportunity to gain clinical experience in the United States, which has broadened his understanding of diverse patient populations and reinforced his commitment to holistic patient care. Outside of medicine, he enjoys running, playing chess, and playing the piano, and stays active through strength training.
